This is a subject I've gotten into many, many times with friends, and I'm not going to get too deep into the discussion (though I already expressed my opinion back on the first page), but I will say this...

Don't you think it's just a little unfair to say "It doesn't matter" when you're not the affected party, and aren't a part of the group that it most often happens to? Or "It doesn't bother me, so it doesn't matter"...because no one else has a valid opinion, of course.
